ok i'm telling you the actual problem...
i have seasonic s12 520w psu... when i power up vga with 2 6pin power connectors...my pc wont start. Even the psu is also not working...whole machine not working

please tell you ideas..where would be the problem..i get that psu brand new..before i had amacroax 500w when i was using it this problem occurred ..so i thougt that problem is in psu and got that seasonic one...but problem is still....
is my vga dead?

It means that Graphics card is consuming too much power, and PSU immediately turns itself off. This can be because of two things:
1) You need a better PSU, because that 9800GTX+ is consuming about 225W, which could be a problem.
2) Your Graphics card is dead, causing short circuit.

Short circuit can be caused if Voltage regulating Mosfets were overheating and heat destroyed them. To repair you need very good soldering skills, multimeter and replacement mosfets, which can be expensive.

225w for a 9800gtx are you for real a 9800gtx probably consumes 100-120w max

Oh, sh.. I am sorry, I overlooked TPU review, it was all system's power consumption.
